More and more cars nowadays are provided with a “Pilot-Assist”. The Dutch-Police-Academy and the Netherlands-Forensic-Institute expect a high potential risk if the Pilot-Assist fails, leaving the vehicle without control and a driver that may not be aware of that. It is of interest how drivers will react during the transition of control from Pilot-Assist to driver. However, this transition has not been studied much. To study this transition, driver simulator tests were performed and the results of these tests were implemented in a model that simulates the transition. It was found that the initial response of all the drivers was to steer in order to keep the vehicle on the road. However, the steer response of every driver was different. It was also found that drivers are significantly more bored while driving with an active Pilot-Assist. A more realistic driving simulator and different test scenarios are needed for further research.
